An ambitious new extreme sports park concept designed by Los Angeles studio M-Rad envisions sustainable power, a shipping container-based luxury hotel, and a variety of sports facilities. Should the proposal become reality, it would be constructed on a sizable 42-acre (17-hectare) plot, just a half block away from the Las Vegas strip.

The Vegas Extreme Sports Park proposal calls for three large towers constructed from shipping containers. One tower will house a growing farm, with the resulting produce sold for profit, while the other two serve as luxury hotels, complete with private infinity pools and rooftop bar.

Adventurous types will be able to partake in the five surf rider wave pools, three zip lines, BMX tracks, skatepark, whitewater rafting and wake-boarding. Each of the activity areas are physically linked by an "XDeck" (a raised platform), containing space for the necessary mechanical equipment and retail sections.

M-Rad also calls for solar power and wind turbines to produce enough energy to provide 85 percent of its energy needs. This seems a tall order, and is probably best taken with a grain of salt, but this huge project does offer an interesting perspective on a possible future of sustainable, large-scale attractions.
